4 things to consider to build a dependable system:
- policy: what you're supposed to achieve
- mechanism: ciphers, or any machinery to implement policy
- assurance: amount of reliance for each mechanism & how well they work together
- incentive: the motive that the people guarding and maintaining
the system have to do their job properly, and also the motive that the attackers have to try to defeat your policy.
